Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Description No power ventilation is running Cause "buzzing" sound is now without power ventilation noise reasons sum up, mainly in the following six: one: no power roof ventilators poorly installed roof ventilator should be installed in suspension can not be crushed by the spring foot bolts. Two: No power roof ventilators installed in contact with the window frame is too tight, hence resulting sash resonance roof ventilator running. Three: No power roof ventilators eliminate vibration seat cushion or set screw too tight, lose eliminate vibration effects, the resulting sound vibrations at work. Four: seat screws loose, bad impeller assembly, excessive speed, shaft mounting screws loosening Workaround: roof ventilator fan base, shaft screw fastening. According to the technical requirements of reassembly, adjust the impeller clearance. Five: Wind Blade chassis collision (cover). Six: bad motor bearings, axial fan base screws loose, fan shaft is not fixed tight top with a hood body blade gap is too small. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. The role of mechanical ventilation axial fans in the grain temperature due to the temperature difference between the larger and the first time to choose the ventilation during the day, in order to reduce the gap between food mild temperatures, reduce condensation occurs. After ventilation as much as possible at night, because this is a cool airy main evening relatively high atmospheric humidity, low temperature, so that reduces moisture loss without power ventilators offer, but also take advantage of the low temperature at night No power roof ventilators, improved cooling effect. When retarder ventilation axial fans, axial fans due to the small amount of wind, in addition to food is a poor conductor of heat, ventilation prone to individual parts of the initial slow airy brand without power ventilators, ventilation continued with full grain temperature warehouse will gradually balance. Slow food carried ventilation must be vibration sieve cleaning, and food into the impurity regions must be promptly cleaned compartment caused the automatic classification, otherwise easily lead to uneven local exhaust ventilation. Advantages to conduct retarder axial fan ventilation: cooling effect is good; low energy consumption, is particularly important in promoting energy today; ventilation and easy to grasp the opportunity, less prone to condensation; not alone with fans, convenient and flexible. Disadvantages: Due to the small amount of wind, a long time ventilation; ineffective precipitation, high moisture grain should be ventilated with axial fans.
